moment.js - UTC不能像我期望的那样工作 [英] moment.js - UTC does not work as i expect it

问题描述

在节点控制台中进行测试：

testing in the node console:

var moment = require('moment');

// create a new Date-Object
var now = new Date(2013, 02, 28, 11, 11, 11);

// create the native timestamp
var native = Date.UTC(now.getFullYear(), now.getMonth(), now.getDate(), now.getHours(), now.getMinutes(), now.getSeconds());

// create the timestamp with moment
var withMoment = moment.utc(now).valueOf()
// it doesnt matter if i use moment(now).utc().valueOf() or moment().utc(now).valueOf()

// native: 1364469071000
// withMoment: 1364465471000
native === withMoment // false!?!?! 

// this returns true!!!
withMoment === now.getTime()

为什么本机的时间戳与wit​​hMoment相同？为什么withMoment返回从当前本地时间计算的时间戳？我怎样才能实现那个时刻.utc（）返回与Date.UTC（）相同的颜色？

why isnt native the same timestamp as withMoment? why does withMoment return the timestamp calculated from the current local-time? how can i achieve that moment.utc() returns the same as Date.UTC()?

推荐答案

致电 moment.utc（）与您调用的方式相同 Date.UTC ：

Call moment.utc() the same way you're calling Date.UTC:

var withMoment = moment.utc([now.getFullYear(), now.getMonth(), now.getDate(), now.getHours(), now.getMinutes(), now.getSeconds()]).valueOf();

我认为打电话给 moment.utc（现在）将假设现在存在于当地时区，它将首先将其转换为UTC，因此存在差异。

I think calling moment.utc(now) will make it assume now lives in the local timezone, and it will convert it to UTC first, hence the difference.
